feat(dialectic): optional structured outputs with limited schema for Dialectic calls (#896)
* Structured outputs for dialectic

* cleanup

* rename json_schema_to_pydantic to clarify it's not a general schema converter

* clean up schema DoS guards

* simplification and cleanup of schema conversion

* chore: ruff and pyproject toml

* chore: basedpyright cleanup in test

* fix: some needed unrelated test failures

* test(schema_conversion-and-anthropic-backend): expand test coverage

include table tests

* fix(llm): support combined tool calling and structured output across backends

- OpenAI: parse() 500s on non-strict function tools; route tool-carrying
  structured requests through create() with an explicit json_schema
  response_format (mirrors the streaming path)
- Anthropic: skip the '{' JSON prefill when tools are present so tool_use
  blocks stay reachable; make the schema instruction conditional and rely
  on parse + repair
- Gemini: native response_schema + function calling is rejected before
  Gemini 3; with tools present, inject a schema instruction into the final
  turn instead and rely on parse + repair
- All backends: tool-call turns carry no consumable content, so skip
  structured-output parsing on them

Extracted from the dialectic structured-output branch (DEV-1652) so the
transport layer can land independently.

* test(live_llm): exercise combined tools + structured output per provider

Two-turn live flow per backend: a forced tool-call turn (structured
parsing must be skipped) followed by a replay turn that must return a
schema-conforming answer with tools still attached. Asserts the
provider-specific request shaping: no parse() for OpenAI (500s on
non-strict tools), no '{' prefill for Anthropic, no native
response_schema for Gemini.

Verified against live OpenAI (gpt-4.1, gpt-5, gpt-5.4, gpt-5.4-mini)
and Gemini (gemini-2.5-flash).

* test(unified): dialectic chat with response_format schema under tool use

Adds response_format pass-through to the unified runner's chat query and
a test case that forces the dialectic tool loop (reasoning off + global
enumeration question) while requiring a schema-conforming JSON answer —
end-to-end coverage of the combined tools + structured output transport
path on whichever provider each level is configured with.

Verified locally against a full harness run (json_match assertions pass;
the llm_judge assertion additionally runs in CI where the Anthropic key
is available).

* fix: some needed unrelated test failures

* ci: add label-triggered live LLM test workflow

Adding the run-live-llm label to a PR (or workflow_dispatch) runs
tests/live_llm/ against real provider APIs — the only place the
--live-llm suite runs in CI. Reuses the unified-tests environment and
its Secrets Manager staging-dotenv resolution for provider keys; runs
on ubuntu-latest (no Fly runner, no Docker — the suite only touches the
LLM backends). Pins LIVE_LLM_ANTHROPIC_45_PLUS_MODELS=claude-sonnet-4-5
since the Anthropic family has no default models and would otherwise
silently collect empty.

Opt-in by design: live model behavior is variable, so this is a signal,
not a required check.

* ci: run live LLM tests on main pushes touching the transport

Mirrors unified-tests' push trigger, scoped to paths that can affect
the live suite (src/llm/, config, the tests, deps, and the workflow
itself) so provider API calls aren't spent on unrelated changes.

* ci: disable auth in live LLM test environment

The staging dotenv sets AUTH_USE_AUTH=true without a usable JWT secret,
and src/config.py validates the pair at import time — the same reason
unified-tests overrides it. This suite never runs the API server.

* test(live_llm): fix gpt-5.4 reasoning_effort and gemini replay-turn flake

- test_live_openai: gpt-5.4 dropped 'minimal' from the reasoning_effort
  vocabulary, so the gpt5 caching test 400'd — and the OpenAI backend's
  BadRequestError terminal swallowed it into an empty CompletionResult.
  Pick the effort per model generation.
- test_live_tools_structured_output: use tool_choice='auto' on the
  replay turn, matching the production dialectic loop (which never
  forces 'none') — NONE mode is what provoked gemini-2.5-flash's empty
  candidates. Drop the temperature pin so retries actually resample,
  and treat a repeat tool call as a retryable attempt.

Verified live: full suite green, gemini 4/4 consecutive passes.

* ci: fail live LLM run when no staging secret was loaded

If the latest-tag fetch fails and no second tag exists, the fallback
step is skipped rather than failed, and the job would proceed without
provider keys — every test then skips via require_provider_key and the
run goes green. Guard on both fetch outcomes so that path fails loudly.

Honcho TypeScript SDK

A high-level, ergonomic TypeScript SDK for the Honcho conversational memory platform. Provides a user-friendly API for managing peers, sessions, and conversational context.

Installation

npm install @honcho-ai/sdk

Usage

import { Honcho } from "@honcho-ai/sdk";

const honcho = new Honcho({
  apiKey: process.env.HONCHO_API_KEY,
  baseURL: "http://localhost:8000",
  workspaceId: "test",
});

const assistant = await honcho.peer("bob");
const alice = await honcho.peer("alice");

await honcho.peers();

const session = await honcho.session("session_1");
await session.addPeers([alice, assistant]);

await session.addMessages([
  assistant.message("What did you have for breakfast today, alice?"),
  alice.message("I had oatmeal."),
]);

const response = await alice.chat("what did alice have for breakfast today?");
console.log(response);

See examples/ for more.

Testing

Tests for the SDK live in tests/ at the monorepo root and are run via pytest, which orchestrates a test server. Do not run bun test directly.

# From the monorepo root
